# scientific calculator

A scientific calculator is a calculator with all the arithmetic^{} capabilities of a basic calculator plus trigonometric, statistical, logarithmic, binary logic, etc. which are useful in various scientific applications. A typical scientific calculator has some forty to fifty keys and is capable of performing about twice as many operations^{} than that (necessitating a “Shift” or “2nd” key). They are often capable of displaying results in binary, octal and hexadecimal, but are usually limited to integers in those bases.

The calculator trigonometric functions are $\mathrm{sin}$, $\mathrm{cos}$, and $\mathrm{tan}$, which have their own keys. The arc versions of these are usually obtainable by using the “Shift” or “2nd” key.

A scientific calculator may have a single memory register with the associated keys M+, MR and MC, but they often have several more registers to hold various values for use in statistical computations.

For values greater than about ${10}^{12}$ or smaller than ${10}^{-12}$ (slightly more or less depending on the model) hardware scientific calculators must switch to scientific notation.
